    <p>The <codeph>pg_tablespace</codeph> system catalog table stores information about the
      available tablespaces. Tables can be placed in particular tablespaces to aid administration of
      disk layout. Unlike most system catalogs, <codeph>pg_tablespace</codeph> is shared across all
      databases of a Greenplum system: there is only one copy of <codeph>pg_tablespace</codeph> per
      system, not one per database.</p>
